Predicting time to transition to psychosis. Cox regression-based estimated cumulative survival functions, indicating the probability of not converting to psychosis, for repetition positivity (RP) z-scores corresponding to the 25^th, 50^th, and 75^th percentiles within the psychosis risk syndrome sample (unmedicated sub-sample). Survival curves showing the estimated risk of transitioning to psychosis over time for baseline RP amplitudes at the 75^th percentile (grey), 50^th percentile (red) and 25^th percentile (blue), illustrating significant (p=.022) predictive relationship between smaller RP amplitudes at baseline and an earlier transition to psychosis.
